SPECIFICATION forming part of Letters Patent No. 477,964, dated June 28, 1892. Application tiled April 22, 1892. Serial No. 430,227. (No model.)

To all whom, it may concern.:

Be it known that I, WILLIAM H. SHEFEIELD, of Brooklyn,in the county of Kings and State of New York, have invented a new and Improved Letter-B0X Hinge, of which the following is a full, clear, and exact description.

My invention relates to improvements in hinges for letter-boxes such as are placed side by side and are usually packed into a small space.

The object of my invention is to produce a hinge by means of which the door ofV the letter-box may be hung from the inside, so that the door may be very nicely finished without exposing the hinge, and also to construct the hinge in such a Way that it will not strike the side partition of the box, which partition comes necessarily very near to the door.

A further object of the invention is to construct the hinge in such a way that it will be very strong and will act as a brace when the door is open.

'lo this end my invention consists in a letterbox hinge, the construction of which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar igures otreference indicate corresponding parts in all the views.

Figure 1 is a front elevation of the letterbox provided with my improved hinge. Fig. 2 is a sectional plan on the line @c :r in Fig. 1, showing the door closed. Fig. 3 is a similar section showing the door open.

The door 10 is hinged to the frame or front 11 of the letter-box, and the door .is provided nearone edge and preferably at the top and bottom with a hinge-arm 12, which is formed.

integral with the door and which extends inward at a right angle to the door, is then bent at a right angle, as shown at 13, and then again at a right angle, as shown at 14, the

perpectly straight, and consequently when the door is open, as shown in Fig. 3, the part 14 will strike the door-frame 11, thus limiting the outward swinging of the door and serving as a brace to prevent the door from being twisted off its hinges.

In letter-boxes of this kind the partitions 17 Valways come very close to the hinge, and this construction enables the-door to be closed Without bringing the hinge-arm into Contact with the partition. In order for the above results to be obtained it is necessary that the parts 12 and 14 of the arm be substantially parallel.

I am aware that it is not new to attach a curved hinge-arm to a door and hang the door from the inner side, and I do not claim such a hinge, broadly, as my invention; but the peculiar form of hinge shown is especially applicable to letter-boxes and enables the letter-box to be nicely finished and strongly made, both these results being obtained at slight expense.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent The combination, with the letter-box and the door, of the U-shaped arm formed integral with the door and having its inner end pivoted to the box, substantially as described.

WILLIAM H. SHEFFELD.
